Print instructions

I believe that 0,25 layer and 15% infill will be just fine. Also that you will not need any supports. No matter if you will use PETG, or PLA. As I have no printer you can send me a photo and information if print works or not. Biggest print can hold coins in value of 879CZK if fully loaded. Medium 346CZK and mini 176CZK. Ive get this idea few days ago when there is more an more online orders and shopping and I need always to pay the exact cost but I never have small change.
UPDATE - Ive made groove smaller so coin will hold better inside.
